Nautical Cricket / Vulcain

A cursory glance at the Vulcain Nautical Cricket might leave you scratching your head. Seemingly random numbers litter the inner dial space, there’s a long aperture revealing even more numbers. It’s a lot to take in right off the bat and can be intimidating to the casual wearer. What’s all this about? These arrangements of numbers are decompression times for divers descending to depths beyond 20 meters. Again, useful stuff for divers in the 60’s or those who go deep sans dive computer. Turning the crown at 4 o’clock adjusts the long aperture on the inner dial, revealing different sets of numbers that correlate necessary decompression times based on the depth of your dive — via HODINKEE
